Using data from a large-scale sales campaign on eBay, I show that successful auction customers punish the seller through unfavorable public feedback when they later learn discover a cheaper fixed-price offer. The probability of receiving such feedback is four times bigger for auctions than for...

In a second-price sequential auction with both global and local bidders, we explore the optimal order for selling heterogeneous goods to maximize efficiency or revenue. Our findings indicate that selling the good with very small variance (almost-zero variance) first yields higher revenue, while...

Public procurement contracts require frequent renegotiation. We exploit the Czech implementation of an EU policy as a natural experiment to investigate the effect of eased renegotiation rules. We document that the eased renegotiation rules decreased winning bids but did not change the final...

Governments can support the green transition through green public procurement. Despite its strategic importance, the impact of this policy on firms remains unclear. Using US data, this paper provides the first empirical analysis of the causal effects of green contracts on corporate environmental...

We consider the problem of allocating multiple units of an indivisible object among a set of agents and collecting payments. Each agent can receive multiple units of the object, and has a (possibly) non-quasi-linear preference on the set of (consumption) bundles. We assume that preferences...

We investigate effects of tax reporting institutions on evasion and incidence using an experimental double auction market setting. We find that 28% of the sellers are truthful when only sellers report, but that 88% and 64% of them are truthful under costless and costly third-party reporting by...

Die Bundesregierung hat im Juli 2022 das sogenannte 'Osterpaket' verabschiedet, das eine Vielzahl an Maßnahmen zum Ausbau erneuerbarer Energien vorsieht. Das Paket hält an der gleitenden Marktprämie als Vergütungsmechanismus fest, welche einseitig nur StromerzeugerInnen absichert, während...

The German Federal Government passed the "Easter Package" in July 2022, which envisages a number of measures for the expansion of renewable energy sources. The package retains sliding market premiums as a remuneration mechanism, which protect electricity producers unilaterally, while contracts...

We study the optimal entry fee in a symmetric private value first-price auction with signaling, in which the participation decisions and the auction outcome are used by an outside observer to infer the bidders' types. We show that this auction has a unique fully separating equilibrium bidding...

Transaction costs are omnipresent in markets yet are often omitted in economic models. We show that their presence can fundamentally alter incentives and welfare in markets in which the price equates supply and demand. We categorize transaction costs into two types. Asymptotically...
